Abstract

A hoist system hoists a flat screen television or a heavy object in a room for attachment to a wall mounted attachment fixture. The hoist system has a wheel-supported base, and a central pillar with a raising and lowering element. The central pillar has a counter weight projection arm with a plurality of notches for carrying a counterbalance weight. A projection arm extends from the movable element in the direction opposite to the counterbalance weight arm with a downward pointing extension that carries a plurality of adjustable L-shaped brackets. The hoist system is brought close to a television or heavy weight at ground level and the L-shaped brackets are inserted therebelow. Weight balance is checked and a counterweight is placed on an appropriate notch in the counterbalance weight arm. The flat screen television or heavy object is then lifted to the correct height for wall attachment. Even though the load produced by the flat screen television or heavy weight being carried overhangs, delivery thereof to a point closely proximate a wall of a room can be reliably and safely accomplished by a single person.

Claims

exact text as granted — not AI-modified
1. A hoist system for hoisting a flat screen television or heavy object in a room or an enclosed space, comprising:
 a. base supported by at least four wheels at least one of said wheels having a locking means, said base having a center; 
 b. said center of said base being integrally connected to a stationary central pillar element; 
 c. a plurality of counter weights; 
 d. said central pillar element having a counterweight extension arm that terminates into a handle at its distal end and has a plurality of spaced notches extending from said central pillar element to said handle for receiving at least one counter weight selected and placed within said notches based on a weight of said flat screen television or heavy object appointed to be hoisted; 
 e. said central pillar having a distal end with an end member, said end member having a raising and lowering element, movable by a displacement means, and wherein said counterweight extension arm is connected to said stationary central pillar at a point below said distal end with said end member; 
 f. said raising and lowering element having a projection arm extending outward in relation to said central pillar and located on the opposite side to and above said counterweight extension arm; 
 g. said projection arm having a downward pointing extension carrying plurality of length adjustable L shaped brackets, wherein said flat screen TV or heavy object is appointed to entirely rest on and be in physical contact with said adjustable L shaped brackets; 
 whereby said L shaped brackets are appointed to be slipped below the bottom of the flat screen television or heavy weight, gently lifted to determine tipping tendency of the load and balanced by a counter weight appointed to be added at an appropriate notch in the counterweight extension arm, the lifted weight balanced flat screen television or heavy weight is appointed to be wheeled to desired location including a local closely proximate to a room wall, lifted to a desired height and attached using a wall attachment means. 
 
     
     
       2. A hoist system as recited by  claim 1 , wherein said raising and lowering element displacement means comprises a screw drive. 
     
     
       3. A hoist system as recited by  claim 2 , wherein said screw drive is turned by a hand crank. 
     
     
       4. A hoist system as recited by  claim 2 , wherein said screw drive is turned by an electric motor drive. 
     
     
       5. A hoist system as recited by  claim 1 , wherein said raising and lowering element displacement means comprises a hydraulic lift mechanism. 
     
     
       6. A hoist system as recited by  claim 1 , wherein said downward pointing extension has two adjustable length L shaped brackets one on each side at the bottom along a line. 
     
     
       7. A hoist system as recited by  claim 1 , wherein said downward pointing extension has an adjustable polypropylene belt attached. 
     
     
       8. A hoist system as recited by  claim 1 , wherein said downward pointing extension is provided with a second projection arm carrying an adjustable vertical support for the lifted object.
